I got my PCB back from uni on friday and have added most of the components, however because i had been using the chip on a breadboard i had set the baud rate for the RS232 connection way down to 19200. Now that i have the chip on a real board it was time to turn it up a bit. The baud rate was hard coded into the bootloader so that needed to be reflashed.

The inital bootloader flash was done at uni using a serial port ISP programmer however i had just cut up my last serial cable and crimped a nice end to match my boards RS232 port so i didnt want to destroy it to flash via ISP. So i dug out this ET-AVR ISP that i purchased ages ago from http://www.futurlec.com.

After Downloading and installing PonyProg from http://www.lancos.com/prog.html (this page didnt work for me in firefox so it was back to Internet Explorer and it was fine). I had to run Pongprog as Administrator to give it access to the parallel port. Then just some configuration in Pongprog
